PROBLEM TO BE SOLVED: To provide a chemical injecting implement in which a catheter can be very easily mounted on a chemical injecting member.SOLUTION: The chemical injecting implement 1 includes the catheter 3 and the chemical injecting member 2. The chemical injecting member 2 includes an injecting member body 4 provided with a chemical inflow space 9 communicating with an opening and a discharge port 8, and a seal part 5 for sealing the opening. The injecting member body has a distribution part 75 communicating with the chemical inflow space 9, and the discharge port 8 has a catheter proximal end part mounting part 87 insertable of the proximal end part of the catheter 3, and an annular projection part 83 for catheter detachment prevention provided inside the catheter proximal end part mounting part 87. The annular projection part includes an annular tapered surface 83a whose diameter is reduced on one end side, and an annular projection end part 83b provided with an inner diameter smaller than the outer diameter of the catheter 3 and formed at an acute angle.COPYRIGHT: (C)2011,JPO&INPIT【課題】薬液注入部材へのカテーテルの装着が極めて容易に行うことができる薬液注入具を提供する。【解決手段】薬液注入具1は、カテーテル3と、薬液注入部材2とからなる。薬液注入部材2は、開口部と連通する薬液流入空間9と排出ポート8とを有する注入部材本体4と、開口部を封止するシール部5とを備える。注入部材本体は、薬液流入空間9と連通する流通部75を備え、排出ポート8は、カテーテル3の基端部の挿入を可能とするカテーテル基端部装着部87と、カテーテル基端部装着部87の内部に設けられたカテーテル抜け止め用の環状突出部83とを備える。環状突出部は、一端側に縮径する環状テーパー面83aと、カテーテル3の外径より小さい内径を有し、かつ鋭角に形成された環状突出端部83bとを有する。【選択図】図7
